摘要 目的探讨单羊膜囊双胎妊娠的产前超声特征。方法回顾性分析40例单羊膜囊双胎妊娠的产前超声声像图特征与产后结局。结果产前超声共检出40例单羊膜囊双胎妊娠,均经产后证实。胎儿畸形发生率为47.5%(19/40),其中双胎反向动脉灌注序列征7例(17.5%);联体双胎5例(12.5%),均为胸脐联胎;双胎腹裂1例(2.5%),胎儿心脏发育异常5例(12.5%),单一胎儿露脑畸形1例(2.5%)。胎死宫内4例,占妊娠总数的10%,其中2例脐带缠绕,2周后复查,均胎死宫内。除胎儿心脏发育异常双胎引产后未做尸解,余均引产后证实。仅17例(42.5%)单羊膜囊双胎妊娠胎儿产前超声检查未见异常。结论单羊膜囊双胎妊娠的胎儿畸形发生率及病死率较高,通过孕早期的超声检查对单羊膜囊双胎妊娠进行早期诊断,中孕期进行胎儿畸形筛查并加强中晚孕期超声监测,降低畸形胎儿出生率及胎儿病死率。
